[description], Story, any other text you want to use. The Cybermagic of Whitelists by: Niall Roche
Before we start getting deep into the meat of this article it's important to explain some standard terminology to make sure the rest of this article makes sense.
A whitelist is a predefined list of IP addresses that are allowed to send email to and receive email from each other. Blacklists exclude known and suspected spammers. Whitelists can be used to exclude everyone except known IP addresses. Think of it like this. A whitelist is a like having a phonebook which is owned by a small group of people who only wish to speak directly to each other. They don't want just anybody ringing them. Not only that but the entire group need to approve new phone numbers before they appear in this exclusive phonebook. To send email to a whitelist you must be approved by the owner of the whitelist. This is a lot like the double optin systems used by legimiate ezines and mailing list owners. Whitelists are the nightclub bouncers of the virtual world - if you ain't on the list you ain't getting in. Simple but very effective. A real world example of a whitelist would be if two companies wanted to exchange email only with each other. These companies could implement a whitelist that contained the IP address for just the two email servers that want to send email to each other. That would mean that any email coming from an IP address not on the whitelist would be returned to sender. For companies they can ensure that employees are only dealing with work related email and not chatting with their friends. The benefits of whitelists are many but proper management of the whitelists is equally important. Misuse of whitelists will only lead to more headaches for everyone involved with missing email, irate customers and IT departments doing overtime just being the tip of the iceberg.

Anyone with a computer and modem can become an electronic publisher of cabletv on the Internet, disseminating information to a global audience. While this new medium explodes with cabletv information, it also poses a vexing problem: How do you evaluate the quality of the cabletv information? Just because a document appears online doesn't mean it contains valid information. In fact online information demands close scrutiny. The publishing world has a long tradition of journalistic standards to which print materials are held. Although many writers and publishers adhere to these standards when publishing on the Web, many don't. It's up to you to cast a critical eye, sorting cabletv fact from fiction, actuality from opinion. Whether you are reading a printed article or an electronic one, a healthy dose of skepticism is in order even when it comes to our cabletv recommendations. Real Time Media On The Net Index
